The master clock driving mammalian circadian rhythms is located in the suprachiasmatic nuclei (SCN) of the hypothalamus and entrained by daily light/dark cycles. SCN lesions abolish circadian rhythms of behavior and result in a loss of synchronized circadian rhythms of clock gene expression in peripheral organs (e.g., the liver) and of hormone secretion (e.g., corticosterone). We examined rhyth...

Circadian rhythms with an endogenous period close to or equal to the natural light-dark cycle are considered evolutionarily adaptive ("circadian resonance hypothesis"). Despite remarkable insight into the molecular mechanisms driving circadian cycles, this hypothesis has not been tested under natural conditions for any eukaryotic organism. We tested this hypothesis in mice bearing a short-perio...

Abstract Radiative cooling passively removes heat from objects via emission of thermal radiation to cold space. Suitable radiative materials absorb infrared light while they avoid solar heating by either reflecting or transmitting radiation, depending on the application. Here, we demonstrate a reflective cooler and transparent solely based cellulose derivatives manufactured electrospinning cast...

Traffic accidents are a leading cause of premature death for citizens, with millions injuries and fatalities occurring annually. Due to the fact that large proportion caused by red light running, reduction frequency running (RLR) has been extensively researched in recent years. However, most previous studies have focused on reducing RLR through driver education or warning sign design, little at...

In line with some previous works, we study in this paper the meson spectrum in the framework of a second order quark-antiquark Bethe-Salpeter formalism which includes confinement. An analytic one loop running coupling constant αs(Q), as proposed by Shirkov and Sovlovtsov, is used in the calculations. As for the quark masses, the case of a purely phenomenological running mass for the light quark...
